Description

[Technical field]

[0001] The present invention relates to a management server and an NFT jacket benefit providing method. [Background technology]

[0002] Traditionally, music CDs and records were sold in disc jackets (hereafter referred to as jackets) along with printed material containing lyrics and artist photos, and for consumers they had value beyond the music. However, with advances in information technology, downloading intangible music data has become the norm, and lyrics, artist photos, etc. can now be easily obtained via the Internet. As a result, the significance of the existence of tangible music CDs and records, and even jackets, has diminished. [Prior art documents] [Patent documents]

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that this is merely an example, and the technical scope of the present invention is not limited to this example. In addition, in all the drawings for explaining the embodiment, the same parts are generally given the same reference numerals, and repeated explanations will be omitted. <System configuration> FIG. 1 is a diagram showing an overview of an example configuration of an NFT jacket privilege providing system in one embodiment of the present invention.

[0013] As shown in FIG. 1, the NFT jacket bonus provision system in one embodiment of the present invention includes a user terminal 100, a bonus information DB 121, and a management server 120 connected to the user terminal 100 and the bonus information DB 121 via a network.

[0014] The user terminal 100 refers to a terminal owned by a user who uses the system according to the present invention. The bonus information DB 121 refers to a server that stores the individual bonus data 310 and the combined bonus data 320. The individual bonus data 310 and the combined bonus data 320 will be described in detail later.

[0015] The management server 120 has a user information memory unit 130, a jacket information memory unit 131, an NFT information memory unit 132, an individual bonus screen memory unit 133, a combined bonus screen memory unit 134, a market screen memory unit 135, an NFT issuing unit 140, an individual bonus screen generation unit 150, a bonus screen providing unit 160, a combined bonus screen generation unit 170, a market screen generation unit 180, and a market screen providing unit 190.

[0016] The user information storage unit 130 stores user information 200 (described later, FIG. 2). The jacket information storage unit 131 stores jacket information 210 (described later, FIG. 2). The NFT information storage unit 132 stores NFT information 300 (described later, FIG. 3). The individual bonus screen storage unit 133 stores an individual bonus screen 800 (described later, FIG. 8). The combined bonus screen storage unit 134 stores a combined bonus screen 1100 (described later, FIG. 11). The market screen storage unit 135 stores a market screen 1400 (described later, FIG. 14).

[0017] The NFT issuing unit 140 obtains from the bonus information DB 121 the user information 200 obtained from the user terminal 100 and individual bonus data 310 corresponding to the NFT issuance key 211 linked to the jacket 110 in the jacket information 210 included in the user information 200, obtains from the bonus information DB 121 combined bonus data 320 corresponding to the case where the combination of NFT issuance keys 211 linked to multiple jackets 110 in the jacket information 210 is a predetermined combination, generates NFT information 300 based on the obtained user information 200, individual bonus data 310 and combined bonus data 320, and issues an NFT 600 in which the NFT information 300 is stored by the blockchain.

[0018] The individual type bonus screen generating unit 150 generates the individual type bonus screen 800 by providing a market screen request tab 840 based on the individual type bonus data 310 and the user information 200 .

[0019] The bonus screen providing unit 160 provides the generated individual bonus screen 800 and combined bonus screen 1100 to the user terminal 100 .

[0020] If the content of the combined bonus data 320 is not “none”, the combined bonus screen generating unit 170 generates the combined bonus screen 1100 by providing a market screen request tab 1140 based on the combined bonus data 320 and the user information 200.

[0021] When the user terminal 100 receives an input from the user pressing the market screen request tab 840 or 1140, the market screen generation unit 180 selects a jacket 110 whose NFT price information 330 included in the NFT information 300 is set to "on sale," and generates a market screen 1400 based on the NFT information 300 of the selected jacket 110 and the user information 200 linked to the jacket information 210.

[0022] The market screen providing unit 190 provides the generated market screen 1400 to the user terminal 100 . <User information storage unit> FIG. 2(a) is a diagram showing an outline of an example of the configuration of user information 200 stored in the user information storage unit 130 of the management server 120 in one embodiment of the present invention.

[0023] As shown in FIG. 2( a ), the user information 200 is made up of data items such as a user ID, a name, account information, a transaction history, and jacket information 210 .

[0024] The user ID indicates a code used by the management server 120 to identify the user. The name indicates the user's name or title. The account information indicates the user's account information. The transaction history indicates historical information regarding past transactions of selling and purchasing NFTs by the user using the system. The jacket information 210 indicates information about the jacket 110 that the user terminal 100 acquires by accepting input from the user (details will be described later).

[0025] 2(b) is a diagram showing an outline of a configuration example of jacket information 210 included in user information 200 stored in user information storage unit 130 of management server 120 in one embodiment of the present invention. Jacket information 210 is composed of data items such as jacket ID, artist information, designer information, NFT issuance key 211, and sound source data. The jacket information 210 is stored in jacket information storage unit 131.

[0026] The jacket ID indicates a code by which the management server 120 identifies the jacket 110. The jacket 110 is a disc jacket for enclosing a music CD or the like, and indicates the jacket purchased by the user.

[0027] Additionally, the jacket 110 in the present invention also includes those that do not enclose a music CD or the like inside. In other words, the jacket 110 refers to an object that is an outer part made of a material such as paper, vinyl, or plastic.

[0028] Artist information indicates information about the artist who created and expressed the sound source recorded on a music CD or the like included in jacket 110. For example, the artist information indicates information such as the name of the artist, the name of the music agency or record company to which the artist belongs, the title of the music CD or the like included in jacket 110, and the name of the music piece.

[0029] Designer information indicates information about the designer who created and expressed the art part and graphic part of the music CD or the like included in jacket 110 or the jacket 110. For example, the designer information indicates information such as the name of the designer and the design office to which the designer belongs.

[0030] The NFT issuance key 211 indicates a key used by the NFT issuance unit 140 of the management server 120 to perform the NFT issuance process (S402, FIG. 4) described later. The NFT issuance key 211 is composed of, for example, a combination of alphanumeric characters, and is associated with each jacket ID one by one. That is, a different unique NFT issuance key 211 is associated with each jacket, and the management server 120 can identify the jacket by referring to the NFT issuance key 211.

[0031] Sound source data indicates information about the sound source recorded on a music CD or the like included in jacket 110. For example, the sound source data is stored in a format such as WAV or MP3. As described above, when jacket 110 does not have a music CD or the like inside, by acquiring the sound source data by downloading or the like, the user can listen to the sound source even without a music CD or the like. <NFT Information Storage Unit> FIG. 3(a) is a diagram showing an outline of a configuration example of NFT information 300 stored in the NFT information storage unit 132 of the management server 120 in an embodiment of the present invention. The NFT information 300 is composed of data items such as a token ID, a jacket ID, owner information, individual type privilege data 310, composite type privilege data 320, and NFT price information 330. Details of the individual type privilege data 310 and the composite type privilege data 320 will be described later.

[0032] The NFT information 300 may also include information in which the combined bonus data 320 is "none." This is because if there is no predetermined combination of NFT issuance keys 211 linked to multiple jackets in the jacket information 210, the NFT issuing unit 140 does not acquire the combined bonus data 320, and the NFT information 300 stores the combined bonus data 320 as "none" (details will be described later with reference to FIGS. 6 and 7).

[0033] Furthermore, the NFT information 300 indicates information about the NFT related to the jacket issued by the NFT issuing unit 140. Note that NFT is an abbreviation for "Non-Fungible Token" and refers to non-substitutable digital data (non-fungible token) created mainly based on blockchain technology.

[0034] The token ID indicates a code used by the management server 120 to identify the NFT.

[0035] The owner information indicates data such as the name or title of the owner of the jacket 110 from which the NFT information 300 was generated, as well as their address, contact information, account information, etc.

[0036] The NFT price information 330 indicates the price of the NFT issued by the management server 120. When a user wishes to sell an NFT, the NFT price information 330 becomes "for sale" and includes an actual selling price, such as "¥4900." On the other hand, when a user does not wish to sell an NFT, the information is stored as, for example, "none."

[0037] The price is determined in advance by the store or record company that sells the jacket 110, but may be determined arbitrarily by the user when reselling the NFT after purchase. Alternatively, the price may be determined as a result of a transaction such as an auction on the market screen 1400 described later. The price is indicated using real currency (dollars, yen, etc.), but may also be indicated using virtual currency.

[0038] Here, the NFT information 300 is data that the NFT has, and is stored in the NFT issued by the NFT generation unit 140 (by a process described later) using blockchain technology. Below, the basic mechanism of the blockchain in this embodiment will be described.

[0039] Blockchain is a technology that, due to its unique data structure and data management methods, makes it possible to provide a transaction ledger that is difficult to tamper with.

[0040] A data block handled by a blockchain is a compilation of one or more transactions that occurred within a certain period of time, and each data block also includes the hash of the previous block. In this way, data blocks containing the hash of the previous block are connected in chronological order like a chain, so if one piece of data is tampered with, all subsequent blocks will need to be re-created. Since re-creating all subsequent blocks requires a huge amount of work, a data structure that is difficult to tamper with is provided.

[0041] Data management is done by distributing the database among individual participants (peers) connected by a P2P (peer-to-peer) network. When any participant distributes a new block, each participant verifies it and adds it to their own data. Then, each participant's verification results are shared via the P2P network.

[0042] In this way, blockchain functions as a huge ledger shared by participants in a P2P network, so blockchain technology allows data to be traded fairly without the risk of tampering, and it is used not only for virtual currencies but also for the exchange of a variety of data.

[0043] In this embodiment, by treating the NFT information 300 as data using blockchain technology, NFT prices, transaction data, etc. can be handled fairly without the risk of unauthorized tampering.

[0044] FIG. 3(b) is a diagram showing an outline of an example configuration of individual bonus data 310 included in NFT information 300 stored in the NFT information storage unit 132 of the management server 120 in one embodiment of the present invention.

[0045] The individual benefit data 310 includes a token ID, an artist photo, a priority reservation ticket, a backstage pass, an event invitation ticket, and the like.

[0046] The artist photo indicates a private photo of the artist who created and performed the sound source recorded on the music CD or the like included in the jacket 110. For example, the artist photo is saved in an image data format such as JPEG.

[0047] The priority reservation ticket indicates a priority reservation ticket for a concert or the like in which the artist who created or performed the sound source recorded on the music CD or the like included in the jacket 110 will appear. For example, the priority reservation ticket is stored as character data such as a number or code, or image data, or the like.

[0048] The backstage pass refers to a pass ticket that invites you to the backstage of a concert or the like in which the artist who created or performed the sound source recorded on the music CD or the like included in the jacket 110 is performing. For example, the backstage pass is stored as character data such as a number or code, or image data, or the like.

[0049] The event invitation ticket indicates an invitation ticket to an event such as a signing session in which an artist who created or performed the sound source recorded on the music CD or the like included in the jacket 110 appears or is held. For example, the event invitation ticket is stored as character data such as a number or code, or image data, etc.

[0050] In addition to the above, the individual bonus data 310 may include unique art content such as a digital copy of artwork, a limited edition design, etc. This allows the individual bonus data 310 to uniquely value these bonuses linked to the NFT. In other words, the NFT has its own unique value, separated from the jacket, which is a tangible object, and the management server 120 can allow users to perform secondary transactions in addition to simple transactions of jackets and sound sources.

[0051] Further, the individual bonus data 310 is linked to all jackets by the record company, artist, designer, etc. and is set and registered in advance, and stored in the bonus information DB 121.

[0052] For example, on the CD album jacket of a certain artist, bonuses such as "priority reservation tickets for the concert at Nippon Budokan on XX / XX date" or "unreleased photos from the music video shoot for the XXth song on the album" are set and registered in advance as individual bonus data 310 by the record company or the like, and are stored in bonus information DB 121 via a network, etc.

[0053] FIG. 3(c) is a diagram showing an outline of an example configuration of composite bonus data 320 included in NFT information 300 stored in the NFT information storage unit 132 of the management server 120 in one embodiment of the present invention.

[0054] The composite bonus data 320 includes a token ID, an artist video, a priority reservation ticket, a discount on limited merchandise, an event invitation ticket, and the like.

[0055] The artist video represents private video of the artist who created and performed the sound source recorded on the music CD or the like included in the jacket 110. For example, the artist video is saved in a video data format such as MP4.

[0056] The limited goods discount indicates a discount coupon for limited goods related to the artist who created or performed the sound source recorded on the music CD or the like included in the jacket 110. For example, the limited goods discount is stored as character data such as a number or code, or image data, or the like.

[0057] In addition to the above, the composite bonus data 320 may also include unique art content such as a digital copy of artwork, a limited edition design, etc. This allows the composite bonus data 320 to uniquely value these bonuses linked to the NFT. In other words, the NFT has its own unique value, separated from the jacket, which is a tangible object, and the management server 120 can allow users to perform secondary transactions in addition to simple transactions of jackets and sound sources.

[0058] Moreover, the composite bonus data 320 is linked to all jackets by the record company, artist, designer, etc., and is set and registered in advance, and stored in the bonus information DB 121.

[0059] For example, for a CD album jacket of a certain artist, bonuses such as "unreleased footage from the music video shoot of the Xth song on the album" or "T-shirt with limited artwork design" are set and registered in advance by the record company or the like as composite bonus data 320, and are stored in the bonus information DB 121 via a network or the like.

[0060] The combined bonus data 320 is composed of bonuses corresponding to a combination of multiple and predetermined jackets. For example, the combined bonus data 320 corresponding to the combination of jackets "A+B+C" does not include the combined bonus data 320 corresponding to the combinations of jackets "A+B" and "B+C".

[0061] For example, different albums by different artists used in a certain popular movie series may be regarded as one set, and bonuses for that set (such as limited edition movie goods) may be set and registered as composite bonus data 320.

[0062] Alternatively, it is conceivable that a record company may pick out a combination of albums by the same artist that are relatively unpopular, and set the composite bonus data 320 as a bonus for that set in order to promote sales.

[0063] The combination of jackets corresponding to the composite bonus data 320 is not particularly limited, and the number of jackets constituting the combination may be, for example, two, three, or four. <Overall processing> FIG. 4 is a diagram showing an overview of the entire process in one embodiment of the present invention.

[0064] First, in S401, the management server 120 performs a user information acquisition process and a jacket information acquisition process (described later with reference to FIG. 5).

[0065] Next, in S402, the management server 120 performs an NFT issuing process (described later in Figures 6 and 7).

[0066] Next, in S403, the management server 120 performs an individual bonus screen generation process (described later with reference to FIGS. 8 and 9).

[0067] Next, in S404, the management server 120 performs an individual bonus screen providing process (described later with reference to FIG. 10).

[0068] Next, if the combined bonus screen 1100 is to be generated, the management server 120 performs a combined bonus screen generation process (described later with reference to FIGS. 11 and 12) in S405. If the combined bonus screen 1100 is not to be generated, the management server 120 proceeds to step S407.

[0069] Next, in S406, the management server 120 performs a combined bonus screen providing process (described later with reference to FIG. 13).

[0070] Next, if the market screen 1400 is to be generated, the management server 120 performs a market screen generation process (described later with reference to FIGS. 14 and 15) in S407. If the market screen 1400 is not to be generated, the management server 120 ends this process.

[0071] Next, in S408, the management server 120 performs a market screen providing process (described later with reference to FIG. 16). <User information storage process> 5(a) is a diagram showing an overview of the user information storage process in one embodiment of the present invention. A method in which the management server 120 stores the user information 200 will be described below.

[0072] First, in S501, the management server 120 provides a user information input screen to the user terminal 100. Next, in S502, the user terminal 100 displays the user information input screen on the display.

[0073] Thereafter, when the user uses the system according to the present invention for the first time, or when the user changes and updates the jacket information 210, in S503, the user terminal 100 accepts input of the user information 200 from the user. Note that the user information 200 accepted from the user at this time includes the jacket information 210.

[0074] Next, in S504, the user terminal 100 transmits to the management server 120 the user information 200 inputted and accepted in S503.

[0075] Next, in S505, the management server 120 receives the user information 200 transmitted in S504, thereby acquiring the user information 200. Next, in S506, the management server 120 assigns a user ID to the received user information 200, and stores the user information 200 inputted in S503 in the user information storage unit 130. Furthermore, the management server 120 stores the jacket information 210 included in the user information 200 in the jacket information storage unit 131. <User information acquisition process> FIG. 5(b) is a diagram showing an outline of user information acquisition processing in an embodiment of the present invention. Hereinafter, a method for the management server 120 to acquire user information 200 will be described.

[0076] When the user uses the system according to the present invention for the second time or later, at S507, the user terminal 100 accepts an input of the user ID from the user. The user ID is included in the user information 200.

[0077] Next, at S508, the user terminal 100 transmits the user ID accepted at S507 to the management server 120.

[0078] Thereafter, at S509, the management server 120 acquires the user information 200 corresponding to the key of the user ID transmitted at S508 from the user information storage unit 130. <Flow of NFT issuance and outlines of individual-type privilege data and composite-type privilege data> FIG. 6 is a diagram showing the flow of NFT issuance and the outlines of individual-type privilege data 310 and composite-type privilege data 320 in an embodiment of the present invention.

[0079] FIG. 6(a) is a diagram showing the flow of NFT issuance and the outline of individual-type privilege data 310 when the NFT has individual-type privilege data 310. As shown in FIG. 6(a), the user 101 owns one jacket 110 (referred to as jacket A) by purchasing it from a store or the like.

[0080] The user 101 acquires the jacket information 210 by means such as reading the QR code (registered trademark) printed on the surface of the owned jacket A using the user terminal 100. For example, the user terminal 100 accesses a predetermined web page by reading the QR code (registered trademark), accepts an input of items (such as the user name) included in the user information 200 from the user within that page, and performs a predetermined authentication procedure or the like to acquire the jacket information 210 linked to the user information 200.

[0081] In this way, the user obtains jacket information 210 including artist information, designer information, NFT issued key 211, sound source data, etc. for the jacket 110 that the user owns.

[0082] When a user uses the system according to the present invention, the user terminal 100 first logs into the system and transmits user information 200 including jacket information 210 to the management server 120 .

[0083] Next, the management server 120 extracts the jacket information 210 from the received user information 200, and further refers to the NFT issue key 211 included in the extracted jacket information 210 to obtain the corresponding individual bonus data 310 from the bonus information DB 121. Note that the individual bonus data 310 corresponding to the jacket A is set and registered in advance in the bonus information DB 121 by the artist or the like.

[0084] After that, the management server 120 generates the NFT information 300 based on the acquired user information 200, jacket information 210, and individual bonus data 310. Then, the management server 120 issues the NFT 600 by storing the NFT information 300 in the blockchain.

[0085] In this way, the issued NFT 600 has individual reward data 310 for jacket A. That is, the management server 120 can provide the user with an NFT that includes, in the blockchain, the limited reward that can be obtained by purchasing an individual jacket.

[0086] Furthermore, by separating the jacket, which is a tangible object, and conducting a buying and selling transaction using only the NFT, which has its own unique value, the management server 120 can allow users to conduct secondary transactions.

[0087] 6(b) is a diagram showing an overview of the flow of issuing an NFT and the composite bonus data 320 when the NFT has the composite bonus data 320. As shown in FIG. 6(b), a user 101 owns multiple jackets 110 (for example, three jackets A, B, and C) by purchasing them from a retailer, etc.

[0088] A user 101 uses a user terminal 100 to obtain jacket information 210 for each of the jackets (A, B, C) that the user owns, for example by reading a QR code (registered trademark) printed on the surface of each of the jackets.

[0089] When a user uses the system according to the present invention, first, the user terminal 100 transmits user information 200, which includes jacket information 210, to the management server 120. The transmitted user information 200 includes jacket information 210 for jackets A, B, and C.

[0090] Next, the management server 120 extracts jacket information 210 for jackets A, B, and C from the received user information 200, and further refers to the NFT issue key 211 contained in each extracted jacket information 210 to obtain the corresponding composite bonus data 320 from the bonus information DB 121.

[0091] That is, the management server 120 acquires the composite bonus data 320 corresponding only to the combination of the NFT issue key 211 for the jacket "A+B+C", and does not include the composite bonus data 320 corresponding to the combination of the jackets "A+B" and "B+C", for example. Also, the composite bonus data 320 corresponding to the jacket combination "A+B+C" is set and registered in advance in the bonus information DB 121 by the artist, etc.

[0092] After that, the management server 120 generates the NFT information 300 based on the acquired user information 200, jacket information 210, and combined bonus data 320. Then, the management server 120 issues the NFT 600 by storing the NFT information 300 in the blockchain.

[0093] In this way, the issued NFT600 has the composite privilege data 320 for jackets A, B, and C. That is, the management server 120 can provide the user with an NFT that includes extremely limited privileges obtained by purchasing a plurality of jackets constituting a predetermined combination on the blockchain.

[0094] Note that in addition to the composite privilege data 320, the issued NFT600 also has individual privilege data 310 for each of the jackets A, B, and C. <NFT Issuance Process> FIG. 7 is a diagram showing an overview of the NFT issuance process in an embodiment of the present invention.

[0095] First, in S701, the NFT issuance unit 140 of the management server 120 acquires the user information 200 from the user information storage unit 130, and further extracts the jacket information 210 included in the acquired user information 200.

[0096] Next, in S702, the NFT issuance unit 140 refers to the content of the NFT issuance key 211 included in the jacket information 210 extracted in S701, and acquires the individual privilege data 310 corresponding to the NFT issuance key 211 for each individual jacket from the privilege information DB121.

[0097] Next, in S703, the NFT issuance unit 140 refers to the NFT issuance keys 211 of the plurality of jackets in the jacket information 210 extracted in S701, and determines whether there is composite privilege data 320 corresponding to a predetermined combination of NFT issuance keys 211.

[0098] Specifically, for example, when there are three jackets A, B, and C, and the NFT issuance keys 211 for each of them are "AA11", "BB22", and "CC33" in order, the NFT issuance unit 140 determines by searching whether there is composite privilege data 320 corresponding to the key "AA11BB22CC33" obtained by combining these in the privilege information DB121.

[0099] The combined bonus data 320 corresponding to a specific combination of NFT issuing keys 211 ("AA11BB22CC33" in the above example) is set and registered in advance in the bonus information DB 121 by the artist, etc. Therefore, if this is not found in the bonus information DB 121, the NFT issuing unit 140 determines that there is "no combined bonus data 320" corresponding to the specific combination of NFT issuing keys 211.

[0100] If there is composite bonus data 320 corresponding to the combination of the predetermined NFT issuing key 211, the NFT issuing unit 140 proceeds to step S704. On the other hand, if there is no composite bonus data 320, the NFT issuing unit 140 proceeds to step S705.

[0101] Next, in S704, the NFT issuing unit 140 obtains from the bonus information DB121 the composite bonus data 320 corresponding to the combination of the specified NFT issuing key 211 referenced in S703.

[0102] Next, in S705, the NFT issuing unit 140 generates NFT information 300 based on the user information 200 acquired in S701, the individual bonus data 310 acquired in S702, and the combined bonus data 320 acquired in S704.

[0103] In addition, if the combined bonus data 320 is "none", the NFT issuing unit 140 generates NFT information 300 based on the user information 200 acquired in S701 and the individual bonus data 310 acquired in S702.

[0104] Thereafter, the NFT issuing unit 140 issues an NFT in which the NFT information 300 generated in S705 is stored by the blockchain. That is, since this NFT stores the NFT information 300 generated in S705 by blockchain technology, the information is non-fungible. Therefore, records of the owner, price, etc. included in the NFT information 300 cannot be tampered with by a third party, and the management server 120 can safely manage the NFT.

[0105] Next, in S706, the NFT issuing unit 140 stores the NFT information 300 generated in S705 in the NFT information storage unit 132.

[0106] Next, in S707, the NFT issuing unit 140 requests the individual bonus screen generating unit 150 to generate the individual bonus screen 800.

[0107] In this way, the management server 120 can issue an NFT that includes on the blockchain various benefits that a user can obtain by purchasing multiple jackets, either individually or in a specified combination. <Individual Benefits Screen> FIG. 8 is a diagram showing an overview of an individual bonus screen 800 according to one embodiment of the present invention.

[0108] 8, the individual type bonus screen 800 includes an NFT information display area 810, an individual type bonus data display area 820, a combined type bonus screen request tab 830, and a market screen request tab 840. The individual type bonus screen 800 is displayed on the user terminal 100.

[0109] The NFT information display area 810 displays the contents of the NFT information 300 generated by the NFT issuing unit 140 for a jacket owned by the user. The NFT information display area 810 displays, for example, "Token ID; T0001", "Jacket ID; J0001", "Owner; XXX", etc. There are no particular limitations on how the NFT information display area 810 is displayed.

[0110] The individual bonus data display area 820 displays the contents of the individual bonus data 310 included in the NFT information 300 generated by the NFT issuing unit 140 for a jacket owned by the user. The individual bonus data display area 820 displays, for example, a "private artist photo," a "priority reservation ticket," a "backstage pass," etc. There is no particular limitation on how the individual bonus data display area 820 is displayed.

[0111] The combined bonus screen request tab 830 indicates a tab for the user to request the combined bonus screen generating unit 170 to generate the combined bonus screen 1100. That is, when the combined bonus screen request tab 830 receives a tap or click input from the user, the management server 120 requests the combined bonus screen generating unit 170 to generate the combined bonus screen 1100. Note that there is no particular limitation on how the combined bonus screen request tab 830 is displayed.

[0112] The market screen request tab 840 indicates a tab for the user to request the market screen generating unit 180 to generate the market screen 1400. That is, when the market screen request tab 840 receives a tap or click input from the user, the management server 120 requests the market screen generating unit 180 to generate the market screen 1400. Note that there is no particular limitation on how the market screen request tab 840 is displayed. <Individual bonus screen generation process> FIG. 9 is a diagram showing an outline of the individual bonus screen generation process in one embodiment of the present invention.

[0113] First, in S901, the individual bonus screen generating unit 150 of the management server 120 acquires from the NFT information storage unit 132 the NFT information 300 required to generate the individual bonus screen 800 requested in S707.

[0114] Next, in S902, the individual bonus screen generating unit 150 extracts the individual bonus data 310 included in the NFT information 300 acquired in S901.

[0115] Next, in S903, the individual bonus screen generation unit 150 refers to the jacket ID included in the NFT information 300 acquired in S901, and extracts the jacket information 210 of the corresponding jacket.

[0116] Next, in S904, the individual bonus screen generating unit 150 extracts, from the user information storage unit 130, the user information 200 linked to the jacket information 210 extracted in S902.

[0117] Next, in S905, the individual bonus screen generating unit 150 generates the individual bonus screen 800 based on the individual bonus data 310 extracted in S902 and the user information 200 extracted in S904.

[0118] Specifically, for example, the individual bonus screen generation unit 150 generates the individual bonus screen 800 by having an NFT information display area 810 that displays "Token ID; T0001," "Jacket ID; J0001," "Owner; ○○○○," etc. by referring to the contents of the extracted user information 200 or NFT information 300, an individual bonus data display area 820 that displays "Private artist photo," "Priority reservation ticket," "Backstage pass," etc. by referring to the contents of the extracted individual bonus data 310, a composite bonus screen request tab 830, and a market screen request tab 840 on the screen.

[0119] Next, in S906, the individual bonus screen generating unit 150 stores the individual bonus screen 800 generated in S905 in the individual bonus screen storage unit 133.

[0120] Next, in S907, the individual bonus screen generating unit 150 requests the bonus screen providing unit 160 to provide the individual bonus screen 800. <Individual bonus screen provision process> FIG. 10 is a diagram showing an outline of a configuration example of an individual type bonus screen providing process in one embodiment of the present invention.

[0121] First, in S1001, the bonus screen providing unit 160 of the management server 120 receives a request to provide the individual bonus screen 800 requested in S907 or the like.

[0126] Next, in S1006, the user terminal 100 determines whether or not a pressing input of the "combined bonus screen request tab 830" has been received from the user. If a pressing input of the combined bonus screen request tab 830 has been received from the user, the user terminal 100 proceeds to step S1007. If a pressing input of the combined bonus screen request tab 830 has not been received from the user, the user terminal 100 proceeds to step S1008.

[0127] Next, in S1007, the management server 120 requests the combined bonus screen generator 170 to generate the combined bonus screen 1100.

[0128] In S1008, the user terminal 100 determines whether or not a press input of the "market screen request tab 840" has been received from the user. If a press input of the market screen request tab 840 has been received from the user, the user terminal 100 proceeds to step S1009. If a press input of the market screen request tab 840 has not been received from the user, the user terminal 100 ends this step.

[0129] Next, in S1009, the management server 120 requests the market screen generator 180 to generate the market screen 1400.

[0130] In this way, the management server 120 can issue an NFT that includes on the blockchain the various benefits that a user can obtain by purchasing an individual jacket, and provide those benefits to the user.

[0131] This means that users can enjoy the exclusive perks that come with purchasing each individual jacket, and then own them as NFTs stored on the blockchain.

[0132] Furthermore, by separating the jacket, which is a tangible object, and conducting a buying and selling transaction using only the NFT, which has its own unique value, the management server 120 can allow users to conduct secondary transactions. <Combined bonus screen> FIG. 11 is a diagram showing an overview of a combined bonus screen 1100 according to one embodiment of the present invention.

If a press input of the market screen request tab 1140 has been received from the user, the user terminal 100 proceeds to step S1309. If a press input of the market screen request tab 1140 has not been received from the user, the user terminal 100 ends this step.

[0153] Next, in S 1309 , the management server 120 requests the market screen generator 180 to generate a market screen 1400 .

[0154] In this way, the management server 120 can issue an NFT that includes on the blockchain a very limited benefit that a user can obtain by purchasing multiple jackets that match a specified combination, and provide that benefit to the user.

[0155] In other words, users can enjoy extremely exclusive rewards by purchasing multiple jackets that match a specific combination, and then own them as NFTs included on the blockchain.

[0156] Furthermore, by separating the jacket, which is a tangible object, and conducting a buying and selling transaction using only the NFT, which has its own unique value, the management server 120 can allow users to conduct secondary transactions. <Market screen> FIG. 14 is a diagram showing an overview of a market screen 1400 according to an embodiment of the present invention.

There is no particular limitation on how the purchase tab 1440 is displayed. <Market screen generation process> FIG. 15 is a diagram showing an outline of the market screen generation process in one embodiment of the present invention.

[0162] First, in S1501, the market screen generation unit 180 of the management server 120 acquires from the NFT information storage unit 132 the NFT information 300 required to generate the market screen 1400 requested in S1009 or the like.

[0163] Next, in S1502, the market screen generation unit 180 extracts the NFT price information 330 included in the NFT information 300 acquired in S1501.

[0164] Next, in S1503, the market screen generation unit 180 references the NFT price information 330 extracted in S1502, selects a jacket that is “on sale”, and extracts the jacket information 210 for that jacket from the jacket information storage unit 131.

[0165] Next, in S1504, the market screen generating unit 180 extracts, from the user information storage unit 130, the user information 200 linked to the jacket information 210 extracted in S1503.

[0166] Next, in S1505, the market screen generation unit 180 generates the market screen 1400 based on the NFT information 300 of the jacket selected in S1503 from the NFT information 300 acquired in S1501, and the user information 200 extracted in S1504.

[0167] Next, in S1506, the market screen generating unit 180 stores the market screen 1400 generated in S1505 in the market screen storage unit 135.

[0168] Next, in S1507, the market screen generation unit 180 requests the market screen provision unit 190 to provide the market screen 1400. <Market screen provision processing> FIG. 16 is a diagram showing an outline of a configuration example of the market screen providing process in one embodiment of the present invention.

[0169] First, in S1601, the market screen providing unit 190 of the management server 120 receives the request to provide the market screen 1400 requested in S1507.

[0170] Next, in S 1602 , the market screen providing unit 190 extracts the market screen 1400 from the market screen storage unit 135 .

[0171] Next, in S1603, the market screen providing unit 190 extracts from the user information storage unit 130 the user information 200 corresponding to the user ID for which the market screen 1400 is to be provided.

[0172] Next, in S1604, the market screen providing unit 190 provides the market screen 1400 to the user terminal 100 by referring to the user information 200 extracted in S1603.

[0173] Next, in S1605, the user terminal 100 displays the market screen 1400 provided by the management server 120 in S1604 on the display of the terminal.

[0174] Next, in S1606, the user terminal 100 determines whether or not it has received an input from the user pressing the sales tab 1430. If it has received an input from the user pressing the sales tab 1430, the user terminal 100 proceeds to step S1607. If it has not received an input from the user pressing the sales tab 1430, the user terminal 100 proceeds to step S1608.

[0175] Next, in S1607, the management server 120 changes the NFT price information 330 for the NFT that the user wishes to sell to “on sale” and stores it in the NFT information storage unit 132.

[0176] Next, in S1608, the user terminal 100 determines whether or not it has received an input from the user pressing the purchase tab 1440. If it has received an input from the user pressing the purchase tab 1440, the user terminal 100 proceeds to step S1609. If it has not received an input from the user pressing the purchase tab 1440, the user terminal 100 ends this step.

[0177] Next, in S1609, the management server 120 changes the “owner information” of the NFT information 300 for the NFT that the user wishes to purchase, and stores it in the NFT information storage unit 132.

[0178] In addition, the management server 120 may generate a certain amount of NFT royalties for the seller (which may be the artist) when a user sells an NFT. The NFT royalties in this case refer to a mechanism in which a portion of the purchase price at the time of the NFT transaction is continuously returned to the selling creator as a secondary distribution fee.

[0179] The management server 120 may also use the NFT to allow the owner of the jacket to put the NFT up for auction or trade with other fans, thereby allowing the management server 120 to promote interaction between fans and the formation of a community.

[0180] In this way, by providing a market screen 1400 that displays jackets owned by other users, the management server 120 can allow users to easily identify and trade the jacket or NFT product they desire.

[0181] Furthermore, since the market screen 1400 has a sales tab 1430 and a purchase tab 1440, the management server 120 can check the jacket details and the NFT before making a transaction, allowing the user to make a safe and satisfying NFT transaction. <Effects of this embodiment> According to the embodiment of the present invention described above, the management server 120 can provide an NFT jacket benefit provision method that issues an NFT that contains on a blockchain various benefits that can be obtained by purchasing multiple jackets that correspond to individual or predetermined combinations, and easily increases the value of the jackets and promotes the activities of artists, record companies, and designers by trading the NFTs.

[0182] In addition, by handling the data as data using blockchain technology, the management server 120 can handle NFT prices, transaction data, etc. fairly without the risk of unauthorized tampering.

[0183] Although the invention made by the present inventor has been specifically described based on the embodiment, the present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made without departing from the gist of the invention. For example, the user terminal includes all user terminals of various types, such as notebook PCs and tablet terminals, in addition to smartphones.

[0184] In addition, the above-mentioned embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the configurations described.
